Liquibase Driver

I am getting the error

SEVERE [liquibase.integration] Cannot find database driver: lib/redshift-jdbc42-2.1.0.16.jar

when trying to specify that liquibase use a redshift driver.

I am using the gitlab docker container FYI.

Should I use redshift-jdbc42-2.1.0.16.jar or liquibase-redshift-4.22.0.jar for the driver or classpath properties and if so how should I specify them?

P.S. It seems to be an issue with not being able to find the driver in the file itself rather than not being able to find the file
